Benefits of technology

The present invention is an electrosurgical apparatus designed to collect smoke generated when a blade is in contact with body tissue easily towards the main body. This is intended to improve the efficiency and effectiveness of the surgery.

Problems solved by technology

Meanwhile, the ESU cuts or coagulates using the principle of high frequency current, and in this process, due to the high temperature of the electrode, moisture in the tissue is evaporated and smoke is generated.
There are substances in the smoke that can adversely affect the health of a doctor who performs the operation.
If the operation is carried out for a long time, the doctor and the nurse may inhale a large amount of smoke, which can seriously harm physical health.
Further, smoke may blur the doctor's vision.

Abstract

An electrosurgical apparatus comprises: a main body formed with a suction passage therein; an extension member including a length adjusting tube coupled to a side of the main body and formed therein with an induction passage communicating with the suction passage, and a sliding part configured to slide while being guided by the length adjusting tube; and a blade configured such that a first end thereof protrudes outside through the sliding part, and a second end thereof extends to be electrically connected to the main body and receives high frequencies from the main body, wherein an entire length of the extension member is adjusted according to a position of the sliding part sliding along the length adjusting tube.

Description

BACKGROUND[0001]The present invention relates generally to an electrosurgical apparatus. More particularly, the present invention relates to an electrosurgical apparatus, in which the smoke generated in the body tissue in contact with a blade is easily collected toward a main body.[0002]In general, an electrosurgical unit (ESU) is a typical medical device that is used to cut a part of human tissue or coagulate tissues and blood using electricity instead of surgical knife, mainly in a surgical operation. The ESU, which utilizes the principle of generating short sparks or heat without causing electric shock or stimulation to the muscles when a high frequency current flows through the human body, is used to cut the desired tissue with a high frequency energy of about 100° C. or coagulate the same with a high frequency energy of about 60° C.[0003]Meanwhile, the ESU cuts or coagulates using the principle of high frequency current, and in this process, due to the high temperature of the e...
